IntroductionThe present study aims to evaluate the efficacy and safety of apatinib monotherapy or combination therapy for patients with advanced or recurrent biliary tract cancer (BTC).
MethodsTwenty-eight patients with advanced or recurrent BTC who progressed after prior systemic therapies and treated with apatinib from January 2017 to June 2019 were enrolled in this retrospective and observational study. The primary end point was progression free survival (PFS). Secondary end points included overall survival (OS), objective response rate (ORR), disease control rate (DCR), and toxicity.
ResultsA total of 28 patients with advanced or recurrent BTC who progressed after prior systemic therapies received apatinib monotherapy or combination therapy (with capecitabine, S-1, oxaliplatin, irinotecan or PD-1 inhibitor), including 9 cases of gallbladder cancer and 19 cases of cholangiocarcinoma. Six patients achieved PR, 15 patients had SD and 7 patients had PD. Median progression-free survival (PFS) and overall survival (OS) was 4.3?months (95%CI?=?1.8-6.8) and 6.2?months (95% CI?=?4.6-7.8) respectively. The ORR and DCR were 21.4% (6/28) and 75.0% (21/28), respectively. Most of the adverse events were grade 1-2 in severity, apatinib treatment was well tolerated.
ConclusionsApatinib monotherapy or combination therapy can improve PFS in patients with advanced or recurrent BTC who progressed after prior systemic therapies, and adverse reactions can be well tolerated. Our study support apatinib therapy as a feasible therapeutic strategy in advanced or recurrent BTC.
